Abstract
The utility model relates to the installation equipment for power lines, especially to an electric wire fixture for erection outside connections. The utility model is characterized in that: an upper clip line groove and a lower clip line groove are provided in an open connector. An expansion core is arranged between the upper clip line groove and the lower clip line groove. A bolt with a cone is provided in the expansion core. The expansion core is displaced by operating the cone bolt so that the conductor wire is fixed.
Description
Invention field
The utility model relates to power line equipment, especially a kind of Electric wire clamp that is used to set up outside line is installed.
Background technology
Connection between the realization power equipment will be used Electric wire clamp.With the traditional electrical wire holder of decades be tabular, electric wire is clipped in wherein uses bolted, because the fastening force of bolt is to the inhomogeneous and dull and stereotyped deformation factor of flat board, the pressure that is subjected to from bolt electric wire far away is little relatively, the inhomogeneous loose contact that causes lead of pressure between electric wire and the flat board, even cause lead and dull and stereotyped oxidation and heating easily, especially when big electric current pressed from both sides by electric wire, this was the one of the main reasons that causes the power line operation troubles.In order to address this problem, often take to increase the method for fastening bolt.Though, increase fastening bolt and can improve contacting and reduce the power line operation troubles between anchor clamps and the electric wire, but can not solve root problem, but also increased the workload of installation and dismounting, along with the continuous development of power circuit, the installation and maintenance problem becomes increasingly conspicuous.In order to make between electric wire and the anchor clamps excellent contact is arranged, China Patent No. 02217549.0 has proposed " a kind of wedge clamp ".The technical scheme of this invention is, be nested with a conical surface body and a conical surface core body, two velamen wire connecting are clipped in respectively between conical surface body and the conical surface core body, and conical surface core body is provided with screw thread, be bolted on the conical surface core body, conical surface body and conical surface core body are by bolt and compress.Though this technical scheme has been improved contacting between lead and the anchor clamps, and fastening also convenient.But the manufacture difficulty of conical surface body and conical surface core body is bigger, and manufacturing cost is also high; In addition, the screw thread on the aluminium alloy conical surface core body can not bear the big pulling force of set bolt, and screw thread has the possibility of inefficacy when bearing big pulling force, and the raising that this has limited the anchor clamps fastening forces has to a great extent also increased operation easier; The fastening force of bolt is too small also may to be caused the tight lead of conical surface core body folder and cause the power line operation troubles.
Summary of the invention
In order to overcome the weak point that existing Electric wire clamp manufacturing cost is high and screw thread lost efficacy easily, the utility model provides a kind of Electric wire clamp, and this Electric wire clamp is not only easily manufactured, and does not have the thread failure problem on the anchor clamps.
The purpose of this utility model is achieved in that clamp groove and following clamp groove is set in a connector that does not seal, and is provided with the expansion core body between last clamp groove and the following clamp groove, is provided with band cone bolt in the expansion core body.The fixing means of lead is: lead sandwiches clamp groove and following clamp groove respectively, can make expansion core body contraction or expansion by the band cone bolt of operating in the expansion core body, and lead can be clamped or be unclamped.
The utility model also can have following further measure on the basis of technique scheme:
The expansion core body is provided with cable clamping interface, and cable clamping interface is arc or triangle.In order to make the expansion core body, also can establish some convex tendons in the cable clamping interface to being produced bigger pressure by the folder lead.
Advantage of the present utility model: because the utility model uses the expansion core body, and by being with the cone bolt to make expansion core body displacement fixing cord.So, there is no need to make taper as the connector of major part, even can process with section bar, this not only helps reducing the manufacture difficulty of connector, but also can reduce the manufacturing cost of connector; Again because of the very high steel manufacturing of band cone bolt usable intensity, so can effectively avoid or reduce the Problem of Failure of screw thread.

Embodiment
Below in conjunction with Fig. 1 to Fig. 6 in detail preferred forms of the present utility model is described in detail:
Better because of the corrosion resistance and the electric conductivity of aluminium alloy, and the characteristics of the low and handling ease of cost are arranged, connector of the present utility model (1) adopts the aluminium alloy manufacturing.Connector (1) is the C type shape that do not seal, and the C type shape connector (1) that does not seal can be articulated in easily on the lead and help installation and removal.C type hole (301) and breach (302) are arranged on the connector (1), and the no conical surface in the connector (1) can make connector (1) utilize the section bar manufacturing that draws easily like this, to reducing manufacturing cost more important meaning is arranged.In order to make connector (1) and bigger contact area to be arranged by the folder lead, clamp groove (2) and following clamp groove (4) are set on the connector (1), last clamp groove (2) and following clamp groove (4), can do in the arc-shaped, expansion core body (5) is installed between last clamp groove (2) on the connector (1) and the following clamp groove (4), expansion core body (5) is provided with cone tank (401) and bolt hole (402), band cone bolt (502) passes bolt hole (402), bolt cone (3) embedding on the band cone bolt (502) is clipped among the expansion core body (5), cone tank (401) on the conical surface (501) and the expansion core body (5) matches, nut (8) is installed on the screw thread (503) of band cone bolt (502), in order to improve expansion core body (5) compressive resistance of aluminium alloy system, add packing ring (6) between nut (8) and the expansion core body (5), packing ring (6) thickness 4mm to 6mm is advisable.
Band cone bolt (502) can be made of one or separable structure.Separable structure is that bolt cone (3) is separated with bolt, and bolt is connected with bolt cone (3) by screw thread, as long as the turn bolt just can make bolt cone (3) at expansion core body (5) internal shift, and expansion core body (5) is expanded and clamping wire.To be with cone bolt (502) to make separable structure and help making and reducing manufacturing cost, install also more convenient.
Arc cable clamping interface (201) core body (5) the large tracts of land contact wire that helps expanding is set on the expansion core body (5).Though, expansion core body (5) and connector (1) but large tracts of land contact wire is but less by the suffered pressure of folder lead, in order to increase by the pressure on the folder lead, establish some convex tendons (601) on the arc cable clamping interface (201) of expansion core body (5), convex tendon (601) can be six to 12.Being noted that that convex tendon (601) is set on the expansion core body (5) is dispensable, is as required and fixed.In addition, the cable clamping interface (201) on the expansion core body (5) can be made triangle or circular arc.
The bolt cone (3) that the utility model diagrammatic sketch provides is square, for easy to process, during actual the manufacturing multiple shape can be arranged, or even conical, coincide with cone tank (401) preferably in order to make bolt cone (3), and conical both sides can process the plane.
